Soft, texturized rubber bumps on this Tangle provide a one-of-a-kind sensory and tactile experience in your hands. The motion is calming and fun! The ability to #fidgettofocus is amazing!

Educators everywhere use Tangles in their classrooms to aid reading and math comprehension and to keep restless minds and hands focused. Please note: Colors may vary. Due to separating segments, the Tangle Jr. is a choking hazard for children. Should not be given to children under 3, and children should be supervised while using.
